OIL our.

Application filed March 25, 1925. Serial No. 18,209.

This invention aims to provide novel means tor lubricating machinery ofany kind, regardless of whether the oil cup is fixed or movable.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that sort to which the inventionappertains.

Although preferred forms have been shown in the drawings, it will beunderstood that a mechanic, working within the scope of what is claimed,may make such changes as his skill may suggest, without departing fromthe spirit of the invention.

In the accompanying drawings Figure 1 showsin longitudinal section, adevice constructed in accordance with the invention, parts being inelevation; Figure 2 is a transverse section on the line 22 of Figure 1;Figure 3 is an elevation showing a slight modification in the valve;Figure 4 is a tragmental longitudinal section showing a modification inthe device delineated in Figure 1; and Figures 5 and 6 are sectionalviews illustrating modifications in that form of the invention. which isillustrated in Figure 4.

Referring particularly to Figures 1 and 2,

there is shown a cup 1, adapted to contain a lubricant, and including areceptacle 2 having a neck 3 which is externally threaded as at 4 forengagement with the part to be lubricated, there being a wrench shoulder5 at the place of juncture between the neck 3 and the cup 1, so that thecup may be turned readily to thread it into place. In the lower end ofthe neck 3 there is a recess 6 communicating with a reduced bore 7which, at its upper end, communicates, with a flared seat 8 formed inthe bottom of the receptacle 2. A closure 9 for the receptacle 2 isprovided, and may be in the form of a cap having a marginal flange 10threaded at 11 on the receptacle 2, the closure 9 having a. wrench lug12 whereby it may be rotated readily. The closur 9 carries a fixedinwardly extended stem 1 1, which is inaccessible when the closure 9 ismounted on the receptacle 2.

The numeral 15 designates a valve including a body 16 having a reducedstem 17, the body 16 having a tapered end 18' adapted to fit in the seat8. The stem 17 of the valve 15 is mounted to reciprocate in the bore 7and is supplied with longitudinal grooves 19.

The device shown in Figure 1 of the drawmgs and above described isadaptedto be mountedon some piece of machinery which moves. The valve 15is located below the stem 14 of the closure 9 and. is spaced slightlytherefrom. As the piece of machinery which carries the cup 1 moves, thevalve 15' will move upwardly and downwardly, the part 18 I of the valvemoving to and from the seat 8, thereby permitting the lubricant to passfrom the receptacle 2 through the grooves 19 to the part tobelubricated.

When it is desired that the part to be lubricated shall have anincreased supply of oil, then the valve 15 is replaced by the valve 20of Figure 3, the valve 20. comprismg a body 21 having a tapered end 22,the stem being designated by the numeral 23 and the numeral 24 markingthe grooves in the stem. It is to be observed that the body 21 of thevalve 20 is shorter than the body 16 of the valve 15. Consequently, thevalve 20 will have an increased amount of play to and from the end ofthe part 14. There maybe as many valves as desired, the valves havingheads of difierent lengths. By substituting one valve for another, theamount of lubricant delivered may be regulated.

In devices of the class described, as hitherto constructed, it has beenthe common practice to limit the movement of such a part as the valve15, adjustably, through the instrumentality of a screw threaded foradjustment into such an element as the cap 9. The disadvantage incidentto the use of an adjustingscrew is that, after one person whounderstands thoroughly the amount of lubriby rendering the stem 14longitudinally adjustable, but, rather, by substituting one valve foranother,'the valves having heads of differentlengths, as illustrated inthe parts 16 and 21. A person expert in lubrication, and well advised asto the amount of.

lubricant required by any particular bearing,

sets up the device as shown in Figure 1, and

there it remains, there being no adjusting screw to be tampered with.

It has been stated hereinbefore that the article shown in Figure 1 isadapted to be movement. vIn the event that it-is desired to use thedevice on a machine part which has no movement, that is, upon a deadbearing when recourse may'be'h'ad to the structure shown in Figure l. Inthat figure,

parts hereinbetore described have been 'des ignated by numeralspreviouslyused, with the sutiix a.

. The'valve ismarked by the numeral 25 and includes a body 26 and astem-27, the groovein the stem being shown at 28. The grooveis extendedlaterally across the. lower end of the body 26 of the valve 25, topermit the passage of lubricant, because the oil cup itself hasnomovcment. Such a valve asthe valve 25 may be replaced by the valve 30ot' Figuref), the body of the valve 30 being designated by the numeral21, the stem being shown at 82, the groove at 33, and the extension at3%. The grooves 33 3a are deeper than the corresponding elements 28%29,and by substitutingsuch' a part as the valve 30 for the valve 25, anincreased flow of oil may be aflorded.

In Figure 6, the valve 30 is shown at 36 and includes a body 37 and astem 38, the stem having grooves 39 on both sides, these grooves beingextended, as shown at a0, along the lower surface of the body 37.

Having thus described the invention, what is claimed is 1. In alubricator of the class described, a, receptacle, a closure for thereceptacle. a stem of determined length fixedly and rigidly secured tothe closure and housed completely within the receptacle, the receptaclehaving an outlet for lubricant, and a valve ,slidably mounted in thereceptacle in substantial alinement with the stem, the valve controllingthe outlet. 1

2. A lubricato'r'of the class described, constructed-as set forth inclaim 1 and further characterized by the provision of means whereby thevalve may be spaced at variable distances from the inner end of thestem.

In. testimony that I claim the foregoing as my own, I have heretoaflixed my signature.
